The color picker used as a theme setting seems to be ok. The issue is when it’s used as a widget setting. I’ve put together a quick plugin to illustrate the issue. Try running this widget in the customizer:

Right, editing the text input field causes a preview refresh, but the color picker by itself does not trigger a javascript change event when the color is changed. I’m hoping the WP Core team can implement a fix for this before releasing 3.9

You should use _.throttle [?] here, because every control change will fire an event immediately which ends in a previewer refresh. I used 3000 here, means the previewer will only refresh once in 3 seconds.

Hi, I have the same problem add a new field in all widget but in the event you add it to a sidebar do not load me the script, specifically a “WpColorPicker’ but I do not load, I only load when save but when dragging no longer works for me.

Sorry, my version is 3.9.2
And if I already realized that this forum is for the Beta. Please add the event when drag a widget load the script. This would serve to make more powerful widget with many options. please….. 🙂

Please don’t post in the Alpha/Beta forum unless you’re actually testing the alpha/beta version of WordPress (not a plugin or a theme). Also, once WordPress has released a version, it’s not appropriate to post in alpha/beta and you should post in the How To & Troublshooting forum:
